Node.js WebSocket 服务器
目前,我尝试为我们的数据库周围的新活动创建一个推送服务器实例。当然,您会找到很多有关该主题的信息。
我正在使用: http://static.brandedcode.com/nws-docs/#s6-p1< /a>
使用以下客户端实现:
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<script src="http://cdn.socket.io/stable/socket.io.js"></script>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.5.2/jquery.min.js"></script>
<title></title>
</head>
<body>
<script type="text/javascript">
(function() {
var webSocket = new io.Socket('ws//test', {
port: 8080
});
webSocket.connect();
webSocket.on('connect',function() {
console.log('Client has connected to the server!');
});
webSocket.on('message',function(data) {
console.log('Received a message from the server!',data);
});
webSocket.on('disconnect',function() {
console.log('The client has disconnected!');
});
window.ws = webSocket;
}());
</script>
</body>
</html>
控制台返回:
Unexpected response code: 404
XMLHttpRequest cannot load http://ws//test:8080/socket.io/xhr-polling//1303822796984. Origin http://test is not allowed by Access-Control-Allow-Origin.
1303822796984GET http://ws//test:8080/socket.io/xhr-polling//1303822796984 undefined (undefined)
我不知道问题所在。
感谢您的帮助。
问候!
currently i try to create a push server instance for new activities around our database. Of course, you find a lot of information about this topic.
I'm using:
http://static.brandedcode.com/nws-docs/#s6-p1
With the following client implementation:
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<script src="http://cdn.socket.io/stable/socket.io.js"></script>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.5.2/jquery.min.js"></script>
<title></title>
</head>
<body>
<script type="text/javascript">
(function() {
var webSocket = new io.Socket('ws//test', {
port: 8080
});
webSocket.connect();
webSocket.on('connect',function() {
console.log('Client has connected to the server!');
});
webSocket.on('message',function(data) {
console.log('Received a message from the server!',data);
});
webSocket.on('disconnect',function() {
console.log('The client has disconnected!');
});
window.ws = webSocket;
}());
</script>
</body>
</html>
The console returns:
Unexpected response code: 404
XMLHttpRequest cannot load http://ws//test:8080/socket.io/xhr-polling//1303822796984. Origin http://test is not allowed by Access-Control-Allow-Origin.
1303822796984GET http://ws//test:8080/socket.io/xhr-polling//1303822796984 undefined (undefined)
I don't know the problem.
Thanks for your help.
Greets!

您正在尝试使用 Socket.io 直接连接到 WebSocket 服务器。
如果您仅运行 WebSocket 服务器而不是 Socket.io 服务器,则可以使用普通的 HTML5 API 连接到 websockets。
例如:
您使用什么浏览器?
目前仅 Google Chrome 支持 WebSocket。在其他浏览器中测试将会失败。
You´re trying to connect directly to a WebSocket server using Socket.io.
If you are running only a WebSocket server and not the Socket.io server, the you can use the normal HTML5 API to connect to websockets.
for example:
What browser are you using?
WebSockets are currently only supported by Google Chrome. Tests in other browsers will fail.
您可能需要
'ws://push.xxx.binder.test'
而不是'ws//push.xxx.binder.test'
(缺少冒号)。You probably wanted
'ws://push.xxx.binder.test'
instead of'ws//push.xxx.binder.test'
(missing colon).更改
为
You no need to add prefix for your domain for socket.io (尤其是斜杠前没有冒号)。另外 var webSocket 也不是一个好的命名 - socket.io 不仅可以使用 websockets (即使在你的错误中它也使用 xhr-poliing )
change
to
You no need to add prefix for your domain for socket.io (especially without colon before slashes). Also
var webSocket
isn't good naming - socket.io can use not onlywebsockets
(even in your errors it usingxhr-poliing
)
